OK, so one of your report summarizers is returning more than what the IReportSummarizer API defines for render_summary: a tuple of template filename and data.

Both of the included summarizers (coverage and testing) can only return that tuple correctly.

So the only logical deduction is that you have another plugin installed that includes a summarizer doesn't conform to the API.

This API was changed in [567] (with the merge of the 0.11 branch) - previously summarizers just returned HTML. So you probably have a plugin installed that generates a summary, but hasn't been updated for the 0.11 branch.

If you disable all your plugins and re-enable one by one you should be able to see which one this is.

I'll mark this as invalid since it's basically a plugin that needs upgrading - please feel free to ask further questions if you're struggling to get this fixed though... and thanks for the report!

You’re right, the build report works well after Eat Lint?-1.0 disabled. Thanks for your advise!
